What is the reason for scanning the local code and coming out directly with the health code?

After scanning the location code, in order not to repeat the bright code, it automatically jumps to the health code, which improves the traffic efficiency. By scanning the "location code", you can automatically register personnel information, automatically verify and display the health information of the "health code", and you can quickly pass it at a glance. In the case of local epidemic situation, it can be traced back to other people who have scanned the "field code" quickly through the scan code records of confirmed cases or close contacts, which is convenient for relevant departments to conduct accurate retrospective investigation and avoid the spread of epidemic situation.
